Je viens d'utiliser le scan online de "Bitdefender", il a trouvé des bestioles mais pas celle qui me dérange, enfin voici le rapport (plus bas) :

Un de mes amis m'a proposé les opérations suivantes, je vais m'exécuter de ce pas:
- Télecharger spybot et ad aware
- Désactiver la restauration du système
- Redemarrer en mode sans échec
- Passer Spybot, Ad aware et Norton
- Vider la quarantaine de Norton
- Redemarrer
